GAS 222.20 Denox
CAUTION
Transport
Transport the product in a way which is not damaging to
health. Where necessary, use auxiliary means for transport
and assembly.
Avoid damage to the product. Treat the product with caution.
Ensure that the product is fastened with wall brackets which
comply with DIN EN 61010-1.
If the device is not used for some time, protect it against heat
and humidity. Store the device in a roofed, dry, and dust free
room. Temperature should be between -20 °C and 60 °C (-4 °F
and 140 °F).

4 Installation and connection

4.1 Installation site requirements

Sample gas probes are intended for flange mounting.
• Installation site and installation position are determined
based on requirements specific to the application.
• If necessary, the connection piece should be slightly tilted
toward the centre of the channel.
• Installation site must be protected from the elements and
should provide protection against sun and rain.
• In addition, adequate and safe access for installation and
future maintenance work should be provided. Particularly
follow the uninstalled size of the probe tube!
• Never over-or underrun the permissible ambient temper-
ature range (T ) of -5 °C to +50 °C (without anti-freeze
amb
heater) or -20 °C to +50 °C (with anti-freeze heater). The
ambient temperature upper limit varies by inlet dew
point and gas composition.
• The dew point must always be at least 5 K above the am-
bient temperature.
• The device must be protected from shock and impact.
If the probe is transported to the installation site in pieces, it
will first need to be assembled.
4.2 Installing the sampling tube (optional)
The sampling tube, if necessary with the fitting extension,
must be screwed in. The probe is then attached to the mating
flange using the included seal, screws and nuts.

4.3 Installing the downstream filter
NOTICE
The downstream filter and the O-ring for the handle must be
inserted prior to first startup.
Operating without downstream filter prohibited!

4.4 Insulation
On heated probes completely insulate any exposed flange
areas and, if applicable, the connection piece to absolutely
prevent thermal bridges. The insulating material must meet
the application requirements and be weatherproof.

4.5 Connecting the gas line

This table provides an overview of the sample gas probe con-
nections:

Gasket inside diameter
Carefully and properly connect the sample gas line to the gas
outlet of the glass pearl receptacle. Please see the drawing be-
low for the fundamental layout of the gas connection:

Attach an O-ring suit-
able for the expected
ambient temperature to
the handle.
Attach the downstream
filter to the handle. Then
carefully insert the
handle with filter in the
gas probe and turn 90°
to secure.
Verify the handle is
seated correctly. When
seated correctly it locks
onto the filter housing.
